Pillai does not limit his scope to electronic transport. He dedicates comprehensive chapters to dielectric physics, explaining polarization mechanisms (electronic, ionic, orientational, and space-charge). He derives the Clausius-Mossotti equation, showing how the local electric field inside a dielectric differs from the applied field. Ferroelectricity, piezoelectricity, and pyroelectricity are discussed with real-world examples like barium titanate and quartz oscillators.

In magnetism, Pillai takes the student from diamagnetism (the weakest response) to ferromagnetism (the strongest). He explains Curie’s law, Weiss’s molecular field theory, and the concept of magnetic domains. The hysteresis loop is explained in detail, linking it to transformer cores and magnetic memory. For the first time, many students understand why iron loses its magnetism above the Curie temperature. Pillai’s ability to break down complex phenomena like antiferromagnetism and ferrimagnetism (ferrites) into digestible pieces is one of the book’s greatest strengths.
